IMPROVEMENT IN DOOR-BELLS The Schedule referred to in these Letters Patent and making part of the same I, WILLIAM ALLronT, of New Britain, in the county of Hartford and State of Connecticut, have invented a new and useful Improvement in House or Door-Bells, of which the following is a specification.

My invention is principally designed for that class of bells to be attached to any part of the house and pulled by a wire, but it may he applied directly to a door. I

The invention consists in the peculiar arrangement of the parts, as hereafter described.

In the accompanying drawings Figure 1 is a front elevation of iny invention, with the bell removed; and

Figure 2 isa front elevation of the bell.

A designates the plate by which the device is secured in position for use, and to which the mechanism is attached.

B is a central post, to which the hell 0 is secured.

.1) designates the hammer attached to a wire spring shaft, a, which is formed into nearly right angles E, immediately below the swinging arms I) b c and 'the trip (I.

The shafta is also coiled after the usual manner of forming wire springs, and its end secured to the stud c in any proper manner.

The arms I) l) c and the trip (1 swing on the pivot f, while the trip (I has a certain degree of play between the arms I) I).

The spiral spring g is attacheddo pins or hooks 71 11-, one of which is secured to the plate A and the other to the arm I), which brings the arm 0 up against the stud i.

By pulling the wire j to the right, the trip cl depresses the hammer-shafta until it has passed the 'eorner of its angular bend E, when the trip will swing in doing so the trip will operate the hammer-shaft a,

as before.

If, in securing the bell in place for use it should be desirable to have it operated by a pull from the left, the spiral spring 1 can he slipped off from the hooks 71 l1, and attached to the hooks 7. k, which will cause the arms to stop with the arm I) in contact with the stud i, when a. pull from the left will operate the mechanism, as before described.

[ claim as my invention .1. The comhination'ot' the hammer D, angular or V-shaped bend E in the hanuncr-shaft a, oscillating trip (I, the swinging arm or lever c, for operating said trip, and the bell U, all combined and operating togather; substantially as described.
